Letters Patent No. 85,202, dated Decemberl 22,1868.

IMPROVEMENT IN CHALK-LINE BOX.

The Schedule referred'to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that. I, SOLOMON BEYL, of Osborn, Greene county, Ohio, have invented an Improved Measuring and Spring Chalk-Line and I hereby declare the following to be an exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which- Figure 1 represents a sideview of the box andtube with rule attached.

Figure 2, a sectional View of the same, showing the mode of chalking the line as it is drawn from thedrum through the upright tube.v

Figure 3 is an end view of the san-1e.

line, the chalk-line heilig wound upon a druln that is operated by a coiled spring, and encased in acylindri-l cal box. To one side of the box I attach an upright tube, into each end of which I insert small boxes coutaining sponge or other elastic material, and the space between the sponge-boxes, I fill with pulverized chalk. When necessary to be used, the line is drawn from the box by' means of the ring at the top of the tube, to which it is attached, and passes through the pulverized chalk and sponge-boxes, and becoming thoroughly coated with chalk during its passage, thereby greatly facilitating the work of the mechanic.

, The line, after being used, is readily carried back to its place in the box by means of the coiled spring.-

The obj ect of the sponge-boxes is to prevent an excess of chalk from being carried out with the line, or

back into the box.

To the upper end ofthe tube is attached a rule that folds down against the side of the tube, and is held Securely in its place by projecting jaws in the .lower part of the tube.

A represents the cylindrical case or box thatcontains the .drum B, upon which the line Gis wound and operated by the coiled spring D.

E is the upright tube, containing the sponge-boxes `F Fand chalk-receptacle G, through which the line i rl.he rule L is for the purpose of'measuring the chalkline as it is drawn out of the box, or Ican be used in measuring any piece of work when the line is not required to be used. l

What I claim as my invention, and desire to secure by Letters Patent, is-A The arrangement of the sponge and cases F F, chalkreceptacle Gr, measuring-rule L, and spring challfline C, 'as herein described, and for the purposes set forth.

SOLOMON BEYL.
